A paper titled Investigation of hit-and-run crash severity through explainable machine learning authored by Stella Roussou, Apostolos Ziakopoulos and George Yannis, has been published in Transportation Letters. This study, uses a 5-year dataset from Victoria, Australia and analyzed with CatBoost algorithms and SHAP values using explainable machine learning techniques, to highlight key severity factors. Findings suggest that the presence of police at the crash scene emerges as the most critical determinant, underscoring the importance of law enforcement in mitigating severe crash outcomes. Furthermore crashes involving passenger vehicles and those on weekends were also linked to higher severity. These novel findings offer valuable insights for targeted interventions and policy-making to mitigate the impact of severe hit-and-run crashes and enhance road safety. 


A paper titled Analyzing the safety effects of different operating speeds for an autonomous shuttle bus service authored by Maria Oikonomou, Marios Sekadakis, Christos Katrakazas and George Yannis has been published in Traffic Safety Research. This study utilizes microscopic simulation analysis in order to quantify the impact of road safety of an automated shuttle bus service within traffic. In the traffic network of Villaverde, Madrid, several scenarios were simulated using the Aimsun software considering the various CAV MPRs and the different operational speeds of the service, namely 15, 30, and 45 km/h. The analysis revealed that the conflict frequency is lower when the shuttle bus operates at 45 or 30 km/h compared to 15 km/h, with the 45 km/h speed showing the largest reduction. This reduction in conflicts is probably due to the shuttle bus adapting more easily to the average traffic speed and is more synchronized with traffic flow. The current study establishes a solid relationship for the conflict frequency of AV shuttles enabling stakeholders to optimize road safety towards a future of automated traffic.

The objective of this Conference is to support the understanding and the execution of suitable approaches to move towards a transportation system without severely injured or killed road users. Due to the rapid progress in the development of powerful computing technology and the enormous potential of artificial intelligence, participants will have the opportunity to uncover the effects of traffic infrastructure, physical conditions, traffic environment and other risk factors, as for example human behaviour, on traffic safety. Researchers can sumbit their abstracts until 15 April 2025. 


The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Traffic Safety Culture Thematic Report which emphasizes on growing a positive Traffic Safety Culture (TSC). This Thematic Report highlights that TSC encompasses shared values, norms, and attitudes that impact behaviours across the road system, influencing not only individual road users but also key stakeholders such as public authorities, private companies, NGOs, vehicle manufacturers, and infrastructure designers. An important way to leverage TSC as a concept to improve road safety is through organisations and companies, also preventive efforts to tackle risk behaviours should be made, ideally by focusing on long-term behavioural change.




The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Professional Drivers Thematic Report which mainly refers to the safety of heavy goods vehicles (HGVs) and buses. This Thematic Report highlights that the safety of HGVs and buses are significantly influenced by road infrastructure due to their unique characteristics such as mass, maneuverability, and acceleration/deceleration capabilities, as well as the fatigue and distraction of the drivers. Furthermore, countermeasures about separating these heavy vehicles from other road users, providing professional drivers with timely warnings about hazardous or restricted road sections and addressing the need for adequate and well-managed overnight parking facilities for HGVs are suggested.




The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Children Thematic Report which refers to the safety of children. This Thematic Report highlights that children are, along with elderly people, the most vulnerable road users with boys being most at risk due to greater exposure and risk-taking behaviour. Moreover, a series of specific countermeasures are suggested, such as road infrastructure that prioritizes vulnerable users, 30 km/h zones around childcare facilities, mandatory protective equipment, the enhancement of active and passive vehicle safety, traffic laws with strict penalties, as well as better Traffic Safety and Mobility education in schools.




The International Road Traffic Safety Analysis and Data (IRTAD) Group and the International Transport Forum (ITF) organized with great success the 39th Meeting which took place in London, UK, on 9-10 April 2025. In this meeting, the latest international road safety developments were discussed. Members and observers from many countries enriched the discussion aimed to improve road safety across the globe. Particular emphasis was given to road safety data collection and analysis. NTUA actively contributed with the following presentation:

The European Commission published the collision matrix for fatalities on rural roads in the EU. The available EU-wide data for 2023 contained in the CARE database, demonstrate that 52% of road traffic fatalities occurred in rural areas, with vulnerable road users (pedestrians, cyclists, e-scooters and users of powered two-wheelers) representing almost 36% of total fatalities. This collision matrix shows clearly that rural road user fatalities occur overwhelmingly when a crash involves cars and heavy vehicles (lorries and heavy goods vehicles). Furthermore, the high number (41% of total fatalities) of fatalities in single vehicle crashes involving cars and motorcycles demonstrate the critical role of speeding on rural roads.



The European Commission published the collision matrix with fatalities on urban roads in the EU. The available EU-wide data for 2023 contained in the CARE database, demonstrate that 38% of road traffic fatalities occured in urban areas, with vulnerable road users (pedestrians, cyclists, users of powered two-wheelers and personal mobility devices) representing almost 70% of total fatalities. This collision matrix shows clearly that urban road user fatalities occur overwhelmingly when a crash involves cars and lorries, underlining the need to improve protection of these vulnerable road users. Furthermore, the high number (44% of the total fatalities) of fatalities in single vehicle crashes of cars and two-wheelers demosntrate the critical role of speeding in the cities.



The European Commission published a breakdown of fatalities in the EU by road user and (other) “main vehicle” involved in the crash. The matrix shows clearly that fatalities overwhelmingly occur in collisions involving cars, and the need to increase the protection of vulnerable road users such as pedestrians, motorcyclists, cyclists and e-scooter riders. EU policies are already evolving in this direction with the new mandatory safety measures introduced by the General Safety Regulation focused on VRUs.
